Studying Kabbalah, I know that you yourself would not want to study, except from one greater than you. And you will not find it except in studying The Book of Zohar. However, prior to each study, resolve within yourself to not make it a habit, but only for the Creator. And not all times are the same: at times you will be able to study for the Creator fervently, if you are rewarded with praying with a pure thought; and sometimes with a small thought, but all with a thought to benefit the Creator.
–The Rav Meshulam Feibush,
Yosehr Divrey Emet (Sincerity, Words of Truth), p 25

If one merits it, he will study The Book of Zohar at dawn, because by its power Israel will come out of exile as out of darkness.
–Ohr Tzadikim veDerech Seuda, Volume 1, Chapter 15

Study in a book of Kabbalah, and even if you do not understand them, say the words of The Zohar, for they can purify the soul.
–The Rav Yaakov Kapil Prayer Book, Section “The Intention in the Study”

It is true that we accept that even for one who knows nothing, the words of The Zohar can still cleanse the soul.
–Rav Tzvi Elimelech Shapira (MAHARTZA),
The MAHARTZA Additions, Item 9

Each and every letter in The Book of Zohar and the writings of our great teacher, by Rav Chaim Vital…are great corrections for the soul, to correct all the incarnations.
–Rav Yitzhak Yehudah Yehiel of Komarno,
Notzer Hesed (Keeping Mercy), Chapter 4, Teaching 20

The system of nature is organized in such a way that everything is aimed only at helping the human level develop. This is the only level of the desire to receive pleasure that has freedom of will. Only this level can raise MAN (a request to the Upper Level) and thus take all the other levels along with it (the inanimate, vegetative, and animate) so all of reality will reach the End of Correction. None of the other levels have freedom of will, but they still take part in the same kind of advancement. They will ascend to the level that the human being brings them to.

For example, according to our time in the year 2010, we should have raised our whole world, including all its levels of inanimate, vegetative, and animate, as well as ourselves on all the levels, and the spiritual world on the inanimate, vegetative, and animate levels (that is, the “chambers,” the “clothing,” the “angels,” and the surrounding souls) ten degrees higher in relation to the Upper Light. We were supposed to make this upgrade in spirit, connection, force, and fulfillment.

Because we did not do this, the inanimate, vegetative, and animate levels of nature are now pressuring us to correct ourselves. All the degrees of fulfillment that they failed to receive from us exist in them in a negative form. They pressure us on the human level since only we have freedom of will and therefore, we need to hasten the correction. Therefore, natural disasters, catastrophes, and disasters will increase in our world because we are not performing the right actions on the human level. We are not drawing all the other levels (the inanimate, vegetative, and animate) after us.

This is the case in the spiritual world as well as in the material world. Therefore, a person depends on everyone and everyone depends on him.
